sagging,
twisting, and flexing (wasn't sure on the scientific terms for these). Can
you
help me out with that one? Or maybe point me to a graph or an equation to

it out?
Thanks in advance for your time,
Jeremy
p.s in the future I will need an eight or 10 foot rod



The sagging could be from a weight of 50 pounds to 100 pounds, twisting
would be
from high torque stepper motors

thanks again people, just slightly confusing with the different numbers
and what
not. And I should have specified the sagging from load, not length.

thanks again, I was worried no one would answer, new here.

thanks
